A Connecticut man has testified in court that he consumed crack, powder cocaine and Percocet pills before killing and dismembering his 90-year-old father.
Jan Gawlik, of New Britain, faces charges of murder and assault on the elderly in the death of his father Joseph and an attack on his 74-year-old mother in October 2011.
The New Britain Herald reports that Alec Buchanan, a former associate professor at the Yale School of Medicine, said in New Britain Superior Court it wasn't drugs but a "psychotic illness" that drove Gawlik. He interviewed Gawlik and others.
Buchanan testified Monday that Gawlik told him he used an ornamental sword and a kitchen knife to stab his father while hearing voices to "dismember" him.
Gawlik's public defender Michael Isko says he'll seek an "extreme emotional disturbance" defense.
